Is Ok. That sounds very convincing indeed ... :) } there a way to debug the problem since it can't even log it to the } /var/log/messages file as everything is just core dumping. - Did you manage to install a more recent kernel ? - Do you use any LKM's ? (A make world might fail to rebuild a LKM, and the incompatible LKM from an earlier build might be left alone in /lkm.) - Can you boot single user (enter "-s" at the "Boot: " prompt, fsck the file systems and mount (r/o) your /var partition ?
